I see. I think I kind of get what you're saying with the jumping -> crouch bhop movement. My criticism here then might be useless as I don't play movement focused games at all (and I never learned to bhop ;-;).
You can reload your gun by... What, getting shot in your hair? Am I understand this correctly?
And whether getting all those mechanics to work well together in a more cohesive level... Yeah I don't know either, but I think if you find more people who play fast-paced movement tech focused games like this their criticism along with your own intuition will naturally drive you to better gameplay and levels.
Looking forward to your next demo even if I suck at this game.
